トするものがある。To explain the operation, when the hydraulic pressure is applied to the right side of the piston 22 and the piston 22 moves to the left side and is pressed against the input case, the rotation of the piston 22 is controlled by the end face support member 25, the cap 33, the spring 32, and the driven member. It is transmitted to the turbine 3 via the plate 31, and the turbine 3
Is fixed to the turbine hub 5, it rotates an output shaft (not shown) via the output hub. Torque fluctuations are absorbed by the spring 32, which is positioned between the end face bearing members 25 and is cut and raised 24.
This prevents axial disengagement. Further, as shown in FIG. 3, the spring 32 for absorbing the torque fluctuation has a double inner spring 32X and outer spring 32Y, and the length of the inner spring 32X is shortened to delay the operation.
It was considered to have the damper characteristics of the step. Also,
To save space, there is one that sets a straight cylindrical spring in an arc shape.
